The CLAST produced by CLooG-ISL contains an assignment and GCC chokes
on it. The exact CLAST contains an assignment followed by an if:
scat_1 = max(0,ceild(T_4-7,8));
if (scat_1 <= min(1,floord(T_4-1,8))) {
S7(scat_1);
}
This is equivalent to a loop that iterates only once, and so CLooG
generates an assignment followed by an if instead of a loop. This is
an important optimization that was improved in ISL, that allows
if-conversion: imagine GCC having to figure out that a loop like the
following actually iterates only once, and can be converted to an if:
for (scat_1 = max(0,ceild(T_4-7,8)); scat_1 <= min(1,floord(T_4-1,8)); scat_1++)
S7(scat_1);
This patch implements the translation of CLAST assignments.
Bootstrapped and tested on amd64-linux.

When setting gloog_error, graphite should continue code generation
without early returns, as otherwise the SSA representation would not
be complete. So set the new expression to integer_zero_node, that
would not require more SSA updates, and continue code generation as
nothing happened.
Regstrapped on amd64-linux.

Propagate the source location of a template's function_decl to the
template_decl built out of it. Without this, specializations
generated before the template was defined get the location of the

gold's ODR checker unhappy.
